Questions, Answered

Everything worth knowing before you build.

What is a chapter ring on a watch?

The chapter ring is the ring that sits between the dial edge and the case, carrying the minute and hour markings around the dial. On SEIKO's SKX models it's a plastic part from the factory; ours is machined brass with printed markings for a crisper, more finished look. Swapping it is one of the simplest cosmetic upgrades in a Seiko mod — a small part with a big effect on how sharp the dial side reads.

Will this chapter ring fit my SKX007?

Yes — it's a direct replacement for the SKX007's original plastic chapter ring, sized as original. It also fits the SKX009, SKX011, SKX171, SKX173, SKX175, our 42mm Diver's watch case, and all 7S26-0020 watch cases.

Does the SKX007 chapter ring have an alignment pin?

Yes — like the original, it keeps the protruding pin at the base that locates the ring and holds the hour and minute markers in alignment with the dial. Fitting is as per the OEM part: seat the pin and the ring sits exactly where SEIKO intended.

Nice Chapter Ring

This chapter ring was perfect for my build. The brushed finish is ideal for the simple black and white layout-it gets the time across without detracting from any other aspect of the build by being too flashy or underwhelming. Perfect alignment too. Would buy again.

Looks good

I bought this for a build I've yet to do, so right off the bat, looks great, but can't comment on fit or looks, once built.

Excellent Chapter ring

Perfect alignment(are you listening Seiko?), zero play with the cantering pin, chapters are aligned perfectly with 60 seconds of space. Numerals are aligned, 12:00 is exactly centred on the space between 6 and 0. The alignment pin is the same size as the socket on the case. Nice work!

Superb service and great products

Chapter ring was perfect for a technical pilot-based watch design. Fit and finish perfect as usual. LA is my favorite mod supplier and always delivers so quickly and attentively.

Does this fit the 36mm explorer case ( ultra thin edition) and if not have you a black CR with 5 minute intervals available that fit? Cheers

Adriel from LuciusAtelier.com

Hi Sean,

Thank you for your inquiry!

All SKX013 chapter rings, whether standard or ultra-thin, are compatible with our 36mm Explorer Watch Case [Ultra Thin Edition]. The ultra-thin chapter rings are designed to accommodate dials with larger indices, ensuring a proper fit without interference. This design aspect pertains to dial compatibility rather than case fitting.

Regarding a black chapter ring with 5-minute intervals, we currently don’t have that specific design available. However, we continually update our inventory, so I recommend checking our website periodically for new additions.

If you have any further questions or need additional assistance, feel free to reach out—I’m here to help!

Best regards,
Adriel

Is there a white variation of this chapter ring with black numerals in order to match a white dial?

Adriel from LuciusAtelier.com

Hello Steven!

Thanks for expressing interest in our mod parts!

>> Is there a white variation of this chapter ring with black numerals in order to match a white dial?
Nope. The closest you can get is silver + black numerals.

Hope this helps. Let me know if you have anymore questions.

Cheers,
Adriel
